Recently found the export file size (from ARC) is much bigger than the same view export from TM1web cube view. it seems more obvious for large/bigger view, e.g. I have data export view having around 5000 rows * 40~50 columns (with both numbers and text), ARC export file size around 5~6MB, where the same view exported from TM1web only around 1MB.
Also it seems it is much slower in ARC export, not sure if it is because a larger file need to be prepared?
It is a Native View, ARC version is 2.2. actually above is tested from our timesheet/expense cube.
